JOHN S. HULL, OF BALTIMORE, MARYLAND.

HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 241,219, dated May 10,1881.

Application filed March 11, 1879.

To all whom it may concern:

Be it known that I, JOHN S. HULL, oi" Ballimore city, State oflllaryland, have invented certain new and useful Improvements inHydrocarbon-Burners and I hereby declare the same to be fully, clearly,and exactly described as follows, reference being had to theaccompanying drawing, in which is illustrated, in side elevation,(partly in section,) an apparatus embodying my present invention.

My said invention relates to apparatus for burning hydrocarbons with anon-luminous or Bunsen flame; and it has for its object to produce anapparatus of that class in which facility is afforded for heating theburner preparatory to allowing the supply of gasoline or equivalentlight hydrocarbon to flow thereto, and which is eminentladapted for usein connection with mechanism for soldering cans or other objectsconstructed of sheet metal, for brazing, and in connection with tinnersfire-pots, or for similar purposes in which it is a desideratum to havean intensely hot and non-sooting flame, and to have it at short noticeand with little trouble.

In so called self-generating gas-burners the liquid hydrocarbon isvaporized in transit to the burner, which latter is first heated bymeans of a lamp or by burning a little gasoline in a cup under theburner. See, for instance, as showing burners of this class, my patentsof April 20, 1880, No. 226,753, and No- Vember 9, 1880, No. 234,282. Irefer to these patents here, moreover, as obviating in this instrument adetailed description of the burner E. This mode of heating the burner isopen to evident objections. It is troublesome and tedious, and resultsin tarnishing and sootin g the burner. I obviate this by providing, inconnection with the supply-tank, an air-pipe communicating with theburner (by preference, leading into the oil-supply pipe) and arranged todeliver to the burner a supply of carbureted atmospheric air, which,being ignited, serves to heat the burner, so that upon cutting off theair-supply and feeding the oil to the burner the latter is caused tovaporize the oil.

Generically, therefore, my invention may be said to consist in thecombination, with a vaporizin g or self-generatin g gas-burner, of agassupply designed to effect the preliminary heating of the burner.Specifically, the invention consists in certain combinations of parts,as hereinafter set forth and claimed.

-In the drawing, A is the tank for containing the oil-supply.

B is an ordinary condensing air-pump.

0 is the supplemental oil-tank, and I) the reservoir for compressed air.

The reservoir A is connected with the burner E by means of pipes a, g,and 'i, and with the pump by means of a pipe, b. The pump is connectedwith the reservoir G by a pipe, 0, terminating in a rose, 0, within thereservoir, and has also a pipe, d, leading to the air-chamber D. Thepipe It opens into the pipe 9, as shown, and the latteris connected withthe bottom of the reservoir 0 by means of a pipe, g. The pipes at l) c dg g h are furnished with cocks a a b d g g h h, designed to cut off oropen communication, as desired, between any two parts of the apparatus.

The reservoir 0 has within it a steam-drum, F, having outlet and inletpipes ff, whereby the gasoline within the tank may be "aporized ifdesired.

In operation, the tanks being charged with oil, the pump is work untilthe desired pressure is reached in the'reservoirs A and D. The cocks band I being then opened, (the others remaining closed,) a supply of airis caused to bubble through the gasoline in the tank 0, and becomingthereby carbureted flows through the pipes g and ito the burner E.Being there ignited the burner is quickly heated, when the gas-supply isshut olf, and the cocks a a g are opened, allowing the oil from the tankA to flow to the burner. As it enters the same it is vaporized, and,mingling with air which is fed through suitable openings in the burner,burns with an intensely hot flame.

It will be seen that each of the chambers A, (1, and D is in directcommunication with the other two and with the burner, and that all theconnecting-pipes are furnished with cocks to set up communication asdesired. Thus the snppl y of oil in the tank 0 may be fed directly tothe burner through the pipe g, the requisite air-pressure being gottenup by working thepump and delivering the air through the By this meansthe working of the burner may be made continuous, as no time need belost in filling the tank A and compressing air therein.

By means of the steam-drum F a supply of hydrocarbon vapor may be fed tothe burner, to be used as the initial heating medium, or the generatedgas may be utilized in lieu of compressed air to feed the oil throughthe pipe g to the burner. The compressed air is, however, to bepreferred, as being safer and more certain in its operation. The drum Fmay, however, be used as a temporary expedient should the pump get outof order. The oil may be forced from the tank A into the tank (J byopening the cocks a a, closing the cock 9', and operating the pump,whereby the airpressure causes the oil to rise in the pipe a and passthence into the tank 0.

I am aware that a carburetor has been used in connection with aburnerfor volatilizing gasoline or equivalent hydrocarbon in transit to aditferel'it burner, and such I do not claim.

What I claim is 1. In combination with the burner E, an oiltank havingpipes leading from its top and bottom to the burner, and having anair-inlet pipe, whereby a supply of carbureted air or of oil may be fedto the burner, as set forth.

2. In combination with the burnerE, an oiltank havingan air-inlet pipetermii'iatingin a rose or equivalent air-distributin g device, and pipesleading respectively from the top and bottom of the tank, and connectedwith the supply-pipe which leads to or supports the burner, as setforth.

3. In combination with the burner E, an oiltank, a carburetor, and anair-chamber, each in communication with the others, whereby a supply ofgas or of oil may be delivered to the burner, as set forth.

4. In combination with the burner E, an airforcing devicecoinmunicatingdirectly with an air-chamber and with an oil-tank, and acarburetor in communication with all the said parts, as and for thepurpose set forth.

5. In combination with the burner E, an airforcing device, and twosupply-tanks, each in communication with the burner, the connecting-pipes being furnished with cooks for setting up orclosingcommunication between the parts at will, as set forth.

6. In combination with the burner E and two supply-tanks, one of whichis furnished with a rose, 0, an air-forcingmechanism, and pipesconnecting the two oil-tanks with each other and with the burner, as setforth.

7. In combination with the oil-chamber A and air-pump B, thecarbnretingchambcr 0, burner E, and pipes a, b, and 0, arranged andoperating as set forth.

8. In combination with the oil-chamber A, pump B, and carburetor O, theair-chamber D, and pipes connecting each with the others, provided withcocks torsetting up the various connections, as set forth.

9. In combination with the oil-chamber A, pump 13, and burner, thecarburetor 0, having rose 0, and the pipes a I) c, as set forth.
